Ask HN: What's the easiest way to set up email forwarding on your own domain?

I've used Google Apps in the past for a simple use case: redirecting email aliases from various personal domains to a gmail.com address. Unfortunately, it's no longer available for free.

Whereas Google Apps is good value as a full service to businesses, $64 per year (UK pricing) per email alias is a bit expensive for this use case.

What would be the most simple replacement for forwarding-only email addresses on your own domains?
